b. Frequency Swing. The peak difference between the maximum and minimum values
of instantaneous frequency. Normally considered as twice the frequency deviation.
LESSON EXERCISES
In each of the following exercises, select the ONE answer that BEST completes
the statement or answers the question.
Indicate your solution by circling the
letter opposite the correct answers in the subcourse booklet.
1. The waveform shown in figure 1-1 represents a portion of a carrier wave being
radiated from a radio transmitter. The frequency and peak voltage outputs of this
transmitter, respectively, are
a. 80 kHz and 5 volts.
b. 80 kHz and 10 volts.
c. 160 kHz and 5 volts.
d. 160 kHz and 10 volts.
Figure 1-1.
Unmodulated carrier wave.
2. Energy can be transmitted over great distances via a radio-frequency carrier
wave.
Intelligence can be "carried" by this wave if any one of its three
characteristics is varied. These characteristics are
a. frequency, phase, and amplitude.
b. starting point, phase, and frequency.
